Matthew 6:9 After this manner therefore pray ye: Our Father which art in heaven, Hallowed be thy name.
Matthew 6:10 Thy kingdom come. Thy will be done in earth, as it is in heaven.
vs 9 is so we recognize the power we speak to and his worthiness of reverence.
vs 10 is so we recognize he is coming back, his will be done in both heaven and earth.
These verses beat down our egos. They are designed to humble us.
When we truly acknowledge that God is in heaven, his name is hallowed, his kingdom, his will and that he controls both places, heaven and earth, we have no room for pride or other such desires of our flesh and our vain imaginations must submit to the power that is so so much more than we are.
Of course we do not quote these words when we pray, we put them into our own words which is much more humbling.
